Improvement in vapor-burners



UNITED STATES- PATENT QEEIcE.

IMPROVEMENT IN VAPOR-BURNERS'.

Specification forming part of Letters Patent No. l 36,022, datedFebruary 18,1873.

To all whom it may concern:

Be it known that we, JOSEPH BENSON and ALBERT H. WATKINs, bothot'Boston, in the county of Suffolk and State of Massachusetts,

' have invented a certain new and useful Improvement in Vapor-Burners;and that the following is a full, clear, and exact description of thesame, reference being had to the accom panying drawing.

The present invention relates to vapor-burn ers, which are adapted to.have a supplementary tlame to more perfectly insure the vaporizing ofthe illuminating liquid 5 and the invention is particularly adapted tovaporburners, constructed, in some degree, as described in ourapplication dated September 23, 12572, for Letters Patent of the UnitedStates, and herein will be explained with particular reference thereto,although it is not intended to limit itk to any one particularvapor-burner.

The invention consists in the application to the burner'tube of a diskmade ot' a cup-shape. This disk is located a short distance below theburner-tip, in position for the supplementary jet to impinge against its'interior periphery, and is of such shape as to fend oli' from thesupplementary jet the upward current of air through the lantern, therebyobviating any liability of its being extinguished bysudden gusts ofwind, &c. y

In the accompanying plate of drawing, our improvement in vapor-burnersis illustrated, Figure l being/ a side view; Fig. 2, a central verticalsection; and Fig. 3, a plan view..

A, in the drawing, represents a vapor-burnv er tube, having burner-tip Band feed-tube C,

as ordinarily. D, a cup-shaped disk, applied to burner-tube A, andsurrounding the same by and through its sleeve E, which lightly ts thetube. The disk D is located just below the burner-tip B, and at itsupper edge a flares or bends inward, as shown. b is the supplementjet-hole.- This jet-hole b is at the lower end of a supplementarychamber, F, about the burner-tube A, and its position is Within thecup-shaped disk, so that the iiame therefrom will impinge against theinterior of the disk D. With the supplementary chamber F communicationis made with the interior of burner-` tube A by and through the innerchamber c of Said tube, which chamber c at its upper end opens to thetube A and at its lower end to the supplementary chamber F, aforesaid,by respective apertures d and f.

The burner, otherwise than above described,

is to be constructed in any of the ordinary y modes, and is to belighted, as commonly with other burners, by re applied to theburnertube, when, as it continues to burn, the supplementary jet, actingin the cup-shaped disk, secures and maintains the proper vaporizin g ofthe illuminating medium employed, and the form of thev disks, as isobvious, feuds from the supplementary jet the upward currents of airalong the burner-tube, preventing thereby the extinguishing of thesupplementary jet from sudden gusts of Wind, &c.

Having thus described our invention, we shall state our claim asfollows:

The burner-tube, havin g the vertical chamber o communicating at itsupper end with the tube A by the aperture (l, and at its lower end withthe double conical-shaped supplemental chamber F by the aperture f, asVherein de-
